This is a tanto by the smith Sadayoshi, who studied under Gassan Sadakatsu, known for his Ayasugi-kitae. Sadayoshi established his forge in Mishima, known for its abundant spring water, and aimed to emulate master smiths of the Koto period like Soshu Masamune and Yamato Hosho Sadayoshi. This particular piece is unusual for Sadayoshi, as it is forged with the Sengoku period smith Muramasa of Ise in mind.
